Currently we have computations of `p_filesz` and `p_memsz` mixed together
with the use of a loop over fragments. After recent changes it is possible to
avoid using a loop for the computation of `p_filesz`, since we know that fragments
are sorted by their file offsets.
The main benefit of this change is that splits the computation of `p_filesz`
and `p_memsz` what is simpler and allows us to fix the computation of the
`p_memsz` independently (D78005 shows the issue that we have currently).

Summary:
Frontend guarantees that coherent accesses have
corresponding cache policy bits set (glc, dlc).
Therefore there is no need for extra instructions
that invalidate cache.

There's an ABI breakage here if LLVM is compiled in C++14 without
aligned allocation and a user tries to use the result with aligned
allocation. If DenseMap or unique_function is used across that ABI
boundary it will break (PR45413). Moving it out of line is a bit of
a band-aid and LLVM doesn't really give ABI guarantees at this level,
but given the number of complaints I've received over this it still
seems worth fixing.
Summary:
This patch maps IR operations for sdiv & udiv to the
@llvm.aarch64.sve.[s|u]div intrinsics.
A ptrue must be created during lowering as the div instructions
have only a predicated form.
Patch contains changes by Andrzej Warzynski.

One of transforms the loop vectorizer makes is LCSSA formation. In some cases it
is the only transform it makes. We should not drop CFG analyzes if only LCSSA was
formed and no actual CFG changes was made.
We should think of expanding this logic to other passes as well, and maybe make
it a part of PM framework.

MCELFObjectWriter::setRType## methods are always used altogether to
build complete MIPS N64 ABI "chain" of relocations. Using single

This reverts commit d254b50b2b5b22368780c6003c419ffa1e23fa93.
The approach here is to create a new (empty) component, `Extensions', where all
statically compiled extensions dynamically register their dependencies. That way
we're more natively compatible with LLVMBuild and llvm-config.

Since every AbstractAttribute so far, and for the foreseeable future,
corresponds to a single IRPosition we can simplify the class structure.
We already did this for IRAttribute but there is no reason to stop
there.
The three tests modified by this commit have been partially disabled
(one run line is commented out). As a consequence subsequent updates
will have weird effects on the check lines. This is a commit to avoid
such effects by making the check lines match the three remaining run
lines.
This reverts commit 9245c7ac13480ed48ae339ad0e68cbe680cd0642.
This is triggering a segfault in XLA downstream, we'll follow-up with
a reproducer, it is likely influenced by TTI/TLI settings or other
options as a simple `opt -loop-vectorize` invocation on the IR
before the crash does not reproduce immediately.
Summary:
Continuing from D77285, the external interfaces implemented by
`ELFDump.cpp` are now declared in `ELFDump.h` and moved into the
`llvm::objdump` namespace. Externs defined in `ELFDump.cpp` that are
unreferenced externally are also made static.

Summary:
* This is a property of the instance of VectorType. If
isa<ScalableVectorType>(T) is true, then T->isScalable() would have
returned true and vice-versa. Most code that checks this function uses
the result to bail out if a vector is a scalable vector. This code will
be cleaner if it just calls isa<ScalableVectorType>(T)

Summary:
Given a VL=14 that is enveloped by a proper VL=16, splitting the
masked load using the enveloping halving VL=8/8 should yields
should eventually yield V=8/5. This fixes various assert failures
in getHalfNumVectorElementsVT() and IncrementMemoryAddress().
Note, I suspect similar fixes will be needed for other masked
operations, but for now I send out a fix for masked load only.

This is a code clean up of the PropertyAttributeKind and
ObjCPropertyAttributeKind enums in ObjCPropertyDecl and ObjCDeclSpec that are
exactly identical. This non-functional change consolidates these enums
into one. The changes are to many files across clang (and comments in LLVM) so
that everything refers to the new consolidated enum in DeclObjCCommon.h.
